| Tiivistelmä: | The existing empirical work on risk-return relation uses relatively small amount conditioning information to estimate the conditional mean and conditional volatility of excess stock market returns. This paper presents methodology for incorporating a large amount of conditioning information in those estimates. It is found that three new factors, "volatility," "risk premium," and "real factors" contain important information about one-quarter-ahead excess returns that is not contained in predictor variables commonly used. Statistically, improvement in out-of-forecasting power is strongly significant and stable over time. The results of the study also support positive conditional risk-return correlation. |
